org.w3c.dom and org.xml.sax

["Anthony Green" <green at redhat dot com>]

org.w3c.dom and org.xml.sax are both part of Sun's SE 1.4 JDK (perhaps even
earlier versions -- I haven't checked).

I believe they use 3rd party implementations for these.  I think we should
use the same implementations (retrieved from http://www.w3.org and
http://www.megginson.com/SAX/index.html).  Here are the classes (although,
they are mostly interfaces)...

I propose that we import this code and use it directly, and I will do this
on Tuesday unless there are any objections.
